Not that I am aware of at the moment.  Does next-20200709 work?  Does
Linus' tree work?  The only obvious thing I can think of is commit

6ec4476ac825 ("Raise gcc version requirement to 4.9")

The commmit message says:

    Using _Generic also means that you will need to have a very recent
    version of 'sparse', but thats easy to build yourself, and much less of
    a hassle than some old gcc version can be.
